Partial activation of SIK3 delays the onset of wakefulness and alleviates hypersomnia due to the lack of protein kinase A-phosphorylation site.

Study Objectives: Sleep/wakefulness is regulated by intracellular signaling pathways composed of protein kinases such as salt-inducible kinase 3 (Sik3). Sik3-deficiency in neurons decreases NREM sleep time and electroencephalogram (EEG) delta power during NREM sleep, while Sik3Slp mice lacking a protein kinase A (PKA)-phosphorylation site, S551, show hypersomnia phenotype. In this study, we examined how a phosphomimetic mutation of the 221st threonine residue (T221E), which provides a partial (weak) constitutive activity of the kinase, affects sleep/wakefulness and circadian behavior.

Attitudes toward subsequent primary cancer prevention among survivors of childhood, adolescent, and young adult (CAYA) cancer in Japan: results of a comprehensive questionnaire survey on long-term women's health after CAYA cancer.

Objective: Prevention of subsequent primary cancer (SPC) is crucial for cancer survivors, particularly those who developed the disease during childhood, adolescence, and young adulthood (CAYA). The aim of this study was to assess the current status of SPC prevention among female CAYA cancer survivors.

Methods: A survey regarding long-term health issues after cancer treatment was conducted using questionnaires that targeted women aged ≥20 years who had developed cancer before the age of 40 years.

Frailty Index Based on Common Laboratory Tests for Patients Starting Home-Based Medical Care.

Objectives: To determine whether a Frailty Index based on laboratory tests (FI-lab) is associated with clinical outcomes independently of a standard nonlaboratory Frailty Index (FI-clinical) in older patients starting home-based medical care.

Design: Secondary analysis of data from a multicenter prospective cohort study.

Setting And Participants: Patients aged ≥65 years who were starting home-based medical care services provided by doctors and nurses at Nagoya, Japan.

Objective physical function declines in the absence of subjective physical complaints among patients with amnestic mild cognitive impairments and mild alzheimer's disease.

Purpose: To examine the extent to which patients with amnestic mild cognitive impairment (aMCI) or Alzheimer's disease (AD) perceive their own physical decline.

Methods: This study included 4450 outpatients (1008 normal cognition [NC], 1605 aMCI, and 1837 mild AD) who attended an initial visit to a memory clinic between July 2010 and June 2021. Their physical function was assessed by the Timed Up and Go test, one-leg standing test, and grip strength.
